WebJan 30, 2024 · Symmetry operations and symmetry elements are two basic and important concepts in group theory. When we perform an operation to a molecule, if we cannot tell any difference before and after we do the operation, we call this operation a symmetry operation. This means that the molecule seems unchanged before and after a symmetry … WebOne of the crucial roles of space groups in crystallography is that they are used to classify the different crystal patterns. The idea here is that two crystal patterns are regarded as equivalent if their groups of isometries are ’the same’. In what sense two space groups …
